Mea Hana Bakteria Aerobic
Wehewehena
He pauka keʻokeʻo ia a ua haku ʻia me nā bacteria a me nā cocci, hiki ke hana i nā spores (endospores).
Loaʻa ma mua o 10-20billion/gram ka nui o nā bacteria ola
Kahua Noi
He kūpono no ke kaiapuni waiwai oxygen o nā mea kanu mālama wai ʻōpala kūlanakauhale, nā ʻano wai ʻōpala kemika a pau o ka ʻoihana, ka paʻi ʻana a me ka hoʻoluʻu ʻana i ka wai ʻōpala, ka leachate ʻōpala, ka wai ʻōpala o ka ʻoihana meaʻai a me nā mālama wai ʻōpala ʻoihana ʻē aʻe.
Nā Hana Nui
1. He hana maikaʻi ka hana hoʻohaʻahaʻa a ka mea bacteria ma luna o nā mea olaola i loko o ka wai. Ma muli o ka ikaika loa o ka pale ʻana o ka bacteria spore i nā mea ʻino o waho. Hiki iā ia ke hoʻonui i ka hiki o ka ʻōnaehana mālama wai ʻino e kūʻē i ka ukana hopena, a he ikaika ka hiki ke lawelawe, hiki i ka ʻōnaehana ke holo pono i ka wā e loli nui ai ka nui o ka wai ʻino, e hōʻoia i ka paʻa o ka hoʻokuʻu ʻana o ka effluent.
2. Hiki i ka mea hana bacteria aerobic ke wehe pono i ka BOD, COD a me TTS. Hoʻomaikaʻi nui i ka hiki ke hoʻopaʻa paʻa i loko o ke kīʻaha sedimentation, hoʻonui i ka helu a me nā ʻano like ʻole o nā protozoa.
3. Hoʻomaka a hoʻōla hou i ka ʻōnaehana wikiwiki, hoʻomaikaʻi i ka hiki ke hana a me ka hiki ke kū i ka hopena o ka ʻōnaehana, e hoʻemi i ka nui o ke koena sludge i hana ʻia me ka maikaʻi, e hoʻemi i ka hoʻohana ʻana i nā kemika e like me ka flocculant, e mālama i ka uila.
ʻAno Hoʻopili
1. Wahi a ka helu kuhikuhi o ka maikaʻi o ka wai i loko o ka ʻōnaehana biochemical o ka wai hoʻoneoneo ʻoihana: ʻo ka mahele mua ma kahi o 80-150 grams / cubic (e like me ka helu ʻana o ka nui o ka loko biochemical).
2. Inā he hopena nui loa ia ma ka ʻōnaehana biochemical i hoʻokumu ʻia e nā loli o ka wai hānai, e hoʻohui i 30-50 grams/cubic i kēlā me kēia lā (e like me ka helu ʻana o ka nui o ka loko biochemical).
3. ʻO ka nui o ka wai hoʻoneoneo kūlanakauhale he 50-80 grams/cubic (e like me ka helu ʻana o ka nui o ka loko biochemical).
Nā kikoʻī
Hōʻike ka hoʻāʻo ʻana he ʻoi aku ka maikaʻi o nā ʻano kino a me nā kemika no ka ulu ʻana o ka bacteria:
1. pH: Ma ka pae o 5.5 a me 9.5, ʻo ka ulu wikiwiki loa ma waena o 6.6-7.8, ua hōʻoia ka hana i ka pono hana maikaʻi loa ma PH 7.5.
2. Mahana: e hoʻomaka ia ma waena o 8℃-60℃. E make nā bacteria inā ʻoi aku ka mahana ma mua o 60℃. Inā haʻahaʻa ia ma mua o 8℃, ʻaʻole ia e make, akā e kaupalena nui ʻia ka ulu ʻana o nā bacteria. ʻO ka mahana kūpono loa ma waena o 26-32℃.
3. Oxygen i hoʻoheheʻe ʻia: ʻO ka oxygen i hoʻoheheʻe ʻia ma ka liʻiliʻi he 2 mg/l i loko o ka pahu hoʻomehana o ka mālama ʻana i ka wai ʻino; ʻo ka metabolism a me ka wikiwiki o ka hoʻohaʻahaʻa ʻana o nā bacteria kūpaʻa kiʻekiʻe i ka mea i manaʻo ʻia e wikiwiki i 5 ~ 7 mau manawa me ka lawa ʻana o ka oxygen.
4. Nā ʻElemene Trace: Pono ka hui bacteria ponoʻī i nā ʻelemene he nui i kona ulu ʻana, e like me ka potassium, ka hao, ka sulfur, ka magnesium, a me nā mea ʻē aʻe. ʻO ka maʻamau, loaʻa iā ia nā ʻelemene lawa i ka lepo a me ka wai.
5. Ka paʻakai: Pili ia i ka wai paʻakai a me ka wai maʻemaʻe, ʻo ka palena kiʻekiʻe o ka paʻakai he 6%.
6. Ke kū'ē ʻana i ka lāʻau make: Hiki iā ia ke pale aku i nā mea ʻawahia kemika, me ka chloride, cyanide a me nā metala kaumaha, a pēlā aku.
